Well, I typed up a long reply and lost it!!! Damn it all!!! I have had my Hosting company looking into it but its a hard one to solve.
I moved your post, hope you don't mind? I want to give CD_Sharp room on his thread.
Some EXCELLENT Points bought up Zanzal!!!
- What is a Magnetic Field?
- What is the Core Doing?
- What happens in the Core?
- Some claim Magical Cores?
Never believe BS! Magical Cores are the complete figment of a delusional Mind!!! Never in a billion years will a “Special Core” be the cause of Basic Electromagnetic Induction! Ever!
First requirement of Electromagnetic Induction is a Changing Magnetic Field in Time! The Magnetic Field is a Polarisation, or an Alignment of Spins, like a series of Spinning Tops, all aligned in a single direction, Polarised with the Magnetic Field
The Magnetic Field is indirectly the cause of Electromagnetic Energy, it is merely a by-product, but at the same time responsible for the Separation of Charged Particles! Which, when in Motion, constitutes a Magnetic Field! Feeling a bit like the Chicken or the Egg situation? Yeah!
So when a Magnetic Field Changing in Time (Source Magnetic Field), Invokes an E.M.F in a Secondary Coil, and a Current is drawn, there is an Equal and Opposite, Action Reaction, effect, a Secondary Magnetic Field. This is a 1:1 less losses, which will be mostly I2R Losses…
This Opposition has some unique characteristics! It is very interesting to study! As the total Magnetic Field increases, the Impedance of the Coils Decrease! This can be seen as the Resistance dropping inside the Coils! Impedance is the combination of the Ohmic DC Coil Resistance, and the Ohmic AC Resistance, the Resistance to Change of the Magnetic Field! Basically, this Ohmic AC Resistance is Lenz’s Law, again in the Coils, creating a reverse pressure, Coil Self Induction, inside the Coils, reducing the ability for the Current to Flow inside the Copper Conductor.
An artificial narrowing of the Pipe to carry a flow of Water is an analogy. We are seeing this Magnetically though!
Yes Magnetic Materials, Cores, do produce effects; they amplify the Magnetic Field to some degree, they Hold Magnetic Flux, allowing a Path of Least Reluctance, lower than Air. All cores do have slightly different characteristics.
But certainly not Magical as some Claim. I was speaking to someone years ago and they said all the Russian Cores were the only cores that work, this is completely false! Much of the Russian Cores come from the same factories ours do! Akula says this also, cores “from China” so don’t be fooled by silliness!
As you correctly point out, as long as we introduce an imbalance between this Equal and Opposite Action, Reaction, and we can do it at no cost to the Input or Output, then we can gain Energy!
Now, a question for all readers: If we have an Equal and Opposite, Action, Reaction, situation in Electromagnetic Induction, and the Input becomes the Output, less losses, then how can we change this situation to increase the output but decrease the Input?
A Clue: Action, Reaction and Counter-Reaction
The number 3 really is a Magic Number!
